Frame ID in Near end & Far end not the same. Make it same at both end Check RSL / Connectorization / Interference in link Check RSL / Connectorization / Interference in link Check RSL / Connectorization / Interference in link IF cable faulty. Repace or redo connectorization MDU Faulty. Replace with good MDU, Connectorisation issue, check CNR setting for AMR



Indicates mismatch in AMR setting in local modem and opposite modem Configuration Header compression setting of local and opposite modems are not the same Configuration MDU Faulty. Replace with good MDU MDU Modem may be faulty. Confirm the same via IF loopback. If no errors in PMON for 15 min time interval on that Modem then Modem not faulty, else faulty MDU Faulty. Replace with good MDU MDU Faulty. Replace with good MDU Local and opposite side Traffic aggregation setting not the same Login to MDU & go to Modem Maintenance Control. Go to XPIC Reset & set Forced Reset. If problem solved else replace MDU Reference Clock failed (when modem is selected as timing source)
